Makes sense to me…

I tend to "graze" on games by regularly(ish) playing for usually not more than an hour. I often swap between games and don't finish many of them. That's never really seemed like the point[0] any more than the idea of "completing" chess or skiing[1]. A tedious, unskippable tutorial level or spending hours early on grinding or subsisting with basic tools/weapons/mechanics before you get the good stuff is what kills a game for me.

So the question for me is how much boredom before it gets fun rather than whether I will eventually lose interest before I finish it. That's a given (I predictably didn't finish Braid or The Witness, I like both).

[0] And besides, like TV series, it just seems like such a lot of time! A game has to be very short or _really_ good, which means both engaging and fun mechanics and a great story, for me to make it to the end.

[1] Ok that's a lie, I definitely intend to complete skiing
